To LZZ whom, it may concern:

Be it known that I, EMIL OcHsNER, a citizenl of the United States,residing at Saronville, in the county of Clay, State of Nebraska, haveinvented certain new and useful Improvements in Incubators; and I dohereby declare the following to be a full, clear, and exact descriptionof the invention, such as will enable others skilled in the art-to whichit appertains to make and use the same.

This invention relates to poultry culture, and more particularly toincubatore, and has for its object to provide an incubator which will beequipped with a novel heating'system of the water type so constructedthat the interior of the incubator may be maintained withall portionsthereof at an even temperature.

A Other objects and advantages will be apparent from the, followingdescription, and it will be understood that changes in the specificconstruction shown and described may be made within the scope of theclaims and that any suitable materials may be used without departingfrom the spirit of the invention.

In the drawings forming a portion of this specification, and in whichlike numerals of reference indicate'similar parts in the several views,Figure 1 is a horizontal section through the present incubator. Fig. 2is a vertical longitudinal section through the body portion and heatingapparatus, taken on line 2 2 of Fig.- 1. Fig. 3 is a top plan view. Fig.i is an enlarged elevation of the heating apparatus, illustrating theair-ports.

Referring now to the drawings, the present incubator comprises a bodyportion 5, having .supporting-legs 6 and having a heating apparatus 7secured to one of its ends. The body portion has horizontaltransversely-extending parallel end pipes 8 and 9 disposed therewithinat its opposite end, which are/connected at their ends bylongitudinally-extending side pipes 10.- The vend pipe 8 is reduced indiameter from its ends to its center, at which point a supply-pipe 11communicates with the pipe 8 and extends outwardly of the body portion.The side pipes 10 at their ends which join the pipe 8 are equal indiameter to that of the last-namedpipe, and the pipes 10 are increasedin diameter from the pipe 8 to the pipe 9, the latter being considerablylarger than the vpipe 8 and being of even diameter throughout its entirelength.

' of position to close the iiue.

heating apparatus 7, the pipe 12 extending p beneath the center of thepipe 8, whereit is directed downwardly at a more abruptangle and 'passesout through the end/wall of the body portion,and this pipe 12 is taperedfrom the pipe 9 to its outer end.

The heating apparatus 7 consists of an outer cylindrical casing 13,having an opening 14: in its bottom, in which there is engaged theuppervend of the chimney 15 of a'heatinglamp 16. Disposed withinthecasingand in spaced relation to the walls thereof there is a cylindricalwater-receptacle 17 having acentral flue 18, which registers with theopening 1 4, `and this receptacle lies in spaced relation to the bottomof the casing 13. A horizontally-extending water-tight partition 19 issecured to the inclosing wall of the casing and tacle 17 to form awater-chamber 20,' and a short vertically-extending pipe 21.connects thechamber 20 with the receptacle 17 for the connected with a thermostat25, located within the body portion for operation of the lever.

. -The pipe 11 communicates with the chamber 20, while the pipe 12 isconnected at its outer end with the receptacle 17 adjacent to the bottomof the latter. formed in the top 27 of the casing 13 and is providedwith a removable cap 28. Formed in the wall of the casing 13 there are aplurality of air-ports 29.

In use the heat from the lamp 16 will circulate through the casing 13and the lues 18 and 22 to heat the water within the chamber 2O and thereceptacle 17, the latter rising and passing out through the pipe 11 toand through the vpipes within the body portion, where it 4will give oii'its heat, and will return through the pipe 12 to the receptacle 17 to beagain heated. When the interior ofthe body portion has reached a certaintemperature', the thermostat 25 will Abe actuated to open the iiue 23,when the draftthus caused will cause The lever 24 is .lies above and inspaced relation to the recep- A filling-port 26 is Ioof air to pass inthrough the ports S29, and this air being of a comparatively lowtemperature will reduce the temperature of the water.

What is claimed is- 1. In an incubator the combination with a bodyportion, of spaced pipes disposed therewithin, one of said pipes beingof greater diameter than the other, the smaller pipe being taperedinwardly from its ends, an outwardlyextending' pipe communicating withsaid smaller pipe at the meeting-point of its tapered portions, taperedpipes communicating at their minor ends with the smaller of thefirstnamed pipes and at their major ends with the larger of thefirst-named pipes, a tapered pipe communicating at itsV major end withthe larger of the first-named pipes between the second-named pipes andextending at its minor end outwardly of the body portion and a fluidheating apparatus disposed outwardly of the body portion said rst andsecond named outwardly-extending pipes communicating with the heatingapparatus at the upper and lower portions thereof respectively.

V 2. In an incubator the combination with a body portion, of fluid-pipesdisposed therewithin, upper and' lower fluid-pipes communicating withthe first-named pipes and tending outwardly of the body portion, acasinglocated exteriorly of thebody portion and having an opening in itsbottom, a heating device disposed to discharge heat through the openinginto the casing, a receptacle disposed within the casing in spacedrelation thereto, said receptacle having a vertical Hue, a horizontalpartition disposed within the casing above the receptacle to form anupper chamber, said chamber having a vertical iiue therethrough, a pipecommunicating with the upper chamber and with the receptacle, a capmovable into and out of position to close the last-named Hue, athermostat, operative connections between the thermostat'and cap, saidupper and lower outwardly-extending pipes communicating with the upperchamber and the receptacle respectively, said casing havingr air-portsformed therein.

In testimony whereof I alix my signature in presence of two witnesses.
